Titan rocket family:
Titan family evolution (LONG) thread:
Titan I was a two-stage, 31m high ICBM. It was the only Titan rocket to use RP-1/LOX, Titan I launched 70 times (suborbitally) between 1959 and 1965.

Starship history thread:
The story of Starship began in 2012 when Elon Musk announced the Mars Colonial Transporter (MCT). It would be capable of launching up to 200t to LEO. The rocket was supposed to have 3 cores with a diameter of >10m, each with 9 engines.

STS-93 - The Golden bullet (thread)
25 years ago yesterday, the Chandra X-Ray Observatory was launched into space aboard Space Shuttle Columbia.
While Chandra successfully reached orbit, the ascent was far from nominal. An engine issue almost sabotaged the whole mission...

During the 40+ years of service, the Space Shuttle Main Engine received many upgrades that increased the engine's performance, reliability, and other factors. A total of 8 RS-25 configurations exist, 7 of them were used on the Space Shuttle

S34, the Penguin
Starship 34 nose cone rolled into the high bay today to stack onto the payload section that rolled in overnight. This is the 2nd next generation Starship Block 2/Version 2 Starship to be built and is expected to launch on flight 8.

NASA'S PLAN TO LAUNCH SOYUZ IN THE SPACE SHUTTLE'S PAYLOAD BAY (a thread)
Before the ISS, NASA planned to build its own space station, Freedom. There was a problem though - the Space Shuttle couldn't stay in space for more than ~ 3-4 weeks. (1/6)

Despite all the issues (and partly thanks to the issues), STS-93 was fully successful, and Chandra is operational to this day
I highly recommend checking out this detailed blog post about what happened, it's a great read.

If you're wondering where Challenger remains are stored, they were placed into launch silos at launch complexes 31 and 32 at Cape Canaveral Space Force Station in 1987. They're expected to stay there forever.

It was used for low-altitude hops. Starhopper performed a 1-meter tethered hop, a 20m hop, and a 150m hop - all in 2019. It remained on the launch site and is used as a mount for cameras and other equipment to this day.

Look how right he was. It was less than 4 weeks.

Probably 3 to 5 weeks.
Objective is for the ship to get past max heating or at least further than last time.

Fun fact: On the Space Shuttle, it used to be quite common for the low-pressure area under the ET to "suck" the exhaust. You can see it very clearly here:

STS-93's primary mission was to deploy the Chandra X-Ray Observatory, Space Shuttle's heaviest payload ever. This was also the first mission commanded by a woman, Eileen Collins. Because of the payload mass, Columbia had only 5 people onboard.

It has now been 84 days since Starship Flight 4.
The gap between Flight 3 and Flight 4 was 84 days.

Fortunately, the pin only ruptured 3 tubes. The engine was safe but the ruptured tubes were leaking 1.6kg of hydrogen every second. The fuel flow sensor was located upstream of the leak, and therefore couldn't detect it and showed nominal flow.

Space Shuttle Orbiter has 3 SSME hydrolox engines. Before LOX gets into the main combustion chamber (MCC), it has to go through a series of posts that inject it into the MCC. Hot hydrogen passes in between those posts and heats up the oxygen.

If you think that Starship's production speed is impressive (it is), look at Atlas's assembly line, early 1960s. Yes, it's real.

Starship SN5 successfully performed a static fire in July 2020. A few days later it successfully performed a 150m hop. Starship SN6 did the same in September 2020.

SSME nozzle is regeneratively cooled, meaning that it's cooled by hydrogen that then continues to the MCC. The nozzle has 1,080 long narrow cooling tubes. It is believed that losing 5 adjacent tubes would cause a burn-through and a chain reaction that would destroy the engine.

1) the disabled damaged post was now operational. Remember that if it failed, it would likely mean a loss of the mission and the crew. The post luckily survived.
2) the free pin flew through the MCC and impacted the nozzle wall.

MCT evolved into the Interplanetary Transport System (ITS) in 2016. ITS would be a fully reusable 2-stage rocket made from carbon composite, running on CH4 and LOX. It was supposed to be capable of launching up to 300t to LEO.

The computer however did detect a lower chamber pressure. Paradoxically, the computer commanded more oxygen (not hydrogen) to be sent to the MCC, which brought the chamber pressure back up.

The first Starship prototype was the Starhopper. It wasn't a full-height prototype as it had no header tanks. Starhopper originally had a nosecone but SpaceX continued without it after it was destroyed by strong winds. Starhopper had a single Raptor engine...

The computer commanded a throttle down on the center engine to reduce the - in reality nominal - chamber pressure. The oxygen (and hydrogen) consumption was therefore reduced and the center engine miraculously made up for the right engine which was using too much oxygen.

That meant that the mixture ratio in the MCC changed. There was more oxygen than there should be, which resulted in higher temperatures. The turbines were 100°C hotter than they should be, the temperature margin was 200°C.

Over the 20 years of Columbia's service, the AC1 cable was being damaged by an overtightened sharp screw head halfway down the payload bay and after liftoff, it shorted.

Unlike the previous prototypes, Starship SN8 had a nosecone and flaps. It performed a 12.5km hop in December 2020. SN8 exploded during the landing maneuver because of low pressure in the header tanks. This was fixed with helium pressurization.

In the end, Columbia ran out of LOX only 0.15 seconds earlier than planned. The oxygen shortfall was only 183kg (it would have been ~10x larger hadn't the AC1 Bus failed) and Columbia's velocity after MECO was only 4.5m/s lower than desired. This was easily corrected with OMS.

With Booster 9, SpaceX changed the separation method to hot-staging (ship engines ignite before the separation occurs). A hot-staging ring was added on top of the booster to achieve this. The booster itself was finished in ~December 2022.

Starship was announced in 2019. It would no longer be made from carbon composites, the material was changed to stainless steel. The ship would now only have 3 sea-level and 3 vacuum Raptor engines and 2 aft flaps.

Starship SNs 12-14 were skipped in favor of a new generation of ships, starting with SN15.
Starship SN15 was the first Starship to complete the high-altitude hop. It launched in May 2021 and successfully landed 6 minutes later.
